in this research anxiety and depression and their association with 32 different factors in students of hamedan university of medical sciences were measured. levels of anxiety and depression were assessed by state-trait anxiety inventory (from 2, trait) and beck depression inventory. a questionnaire made of demographic data, educational and noneducational activities, the presence of medical or p...

We answer the question: If a vacuum sector Hamiltonian is regularized by an energy cutoff, how one-kink regularized? find that it not indeed normal modes of all energies are present in kink Hamiltonian, but rather decomposition field into mode operators yields coefficients which lie on constrained surface forces them to become small for above cutoff. This explains old observation cutoff leads i...

The electromagnetic acoustic transducer (EMAT), a non-contact NDT tool with large lift-off, is becoming an attractive method for detecting the cracks in the metal parts. However, the lift-off of the transducer has a direct effect on the feature that is used to characterize the defects. A detailed investigation on the relationship between the feature and the lift-off of the EMAT is crucial in th...

chitosan/polyethersulfone (cs/pes) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. the substrate membrane was prepared by phase inversion technique using polyethersulfone (pes) and dimethylacetamide (dmac) as solvent with and without the addition of polyvinylpyrrolidone (pvp) as pore-forming agent. the effects of the composition of the c...

— The propagation of elastic surface waves, guided by the free surface of an infinitely long cylinder, of arbitrary cross section, is formulated as on eigenvalue problem, for an unbounded self adjoint operator. We prove the existence of a hierarchy of guided modes. Two of them propagate for any value of the wave number, whereas all of the others only exist beyond a cut-off wave number. For any ...

This study assessed healthy young adults to determine the normal limits for electrocardiographic variables and cut-off values for left ventricular hypertrophy. It was a cross sectional descriptive study in which the participants were evaluated clinically by standard 12-lead resting electrocardiogram (ECG) at 25 mm/s during quiet respiration. The heart rate, P wave duration, axis and amplitude, ...

For the Schrödinger-Poisson system, we propose an ALmost EXact(ALEX) boundary condition to treat accurately the numerical boundaries. Being local in both space and time, the ALEX boundary conditions are demonstrated to be effective in suppressing spurious numerical reflections. Together with the Crank-Nicolson scheme, we simulate a resonant tunneling diode. The algorithm produces numerical resu...
